Genetic Screening

How It Works:

• Genetic screening uses techniques similar to those in DNA profiling.
• It identifies mutated genes by detecting abnormal or altered DNA sequences.
• Mutated genes are responsible for genetic disorders, such as:
  • Cystic fibrosis: A build-up of mucous in the lungs.
  • Hemochromatosis: A build-up of iron in the body.

Applications of Genetic Screening:

• If a couple knows one or both partners have a gene mutation, they can be informed about the likelihood of passing the disorder to their child.
• Based on this information, they can decide whether or not to have a child.

Ethical Considerations:

• If an embryo is tested and shown to have a genetic disorder, this may lead the couple to consider abortion.
• Such decisions raise important ethical issues about the use of genetic screening and its impact on families and society.
